Archaeologists have unearthed a unique Aramaic inscription, on a stone excavated on Jerusalem's Mount Zion. But the phrase is written in such an odd way experts fear it will take months to understand. The stone, believed to have been created around the city's Second Temple Period (516 BC - 70 AD), was found inside a house complex which has already proffered a mikve ritual bath and three bread ovens. %QUOTE Shimon Gibson, who is leading the University of North Carolina dig at the site, was enthralled by the remarkable stone, but warned it would be at least two months before anyone could decipher its clear but cryptic message. "This is a difficult script, not one that is worn or graded, which demands research," he told the Jerusalem Post.
